As soon as projects a presser foot bar 13 whose outer end is the jack is contracted, the spring 17 will return Provided With a rearwldly directed prong or the presser foot member to normal position so 5 that no manual elort is required to accomplish the same.

It will be seen that the present device is extremely simple and durable in construction and may be readily employed in commotion with an ordinary portable jack for emciently forcing a tire from its rim. Also, it. will be seen that the device will be exceedingly light in weight and may be made so small as to require little storage space when not in use, as well as being capable of being readily handled when required for use. By adapting the device for use in connection with an ordinary portable jack, the device requires no self-contained jacking mechanism, and therefore possessesthe advantage of simplicity and lightness over tire-removing tools having selfcontained jacking mechanisms.

From the foregoing description, it is believed Qthat the construction, operation and advantages of the present invention will be readily understood and appreciated by those skilled in the art. Minor changes are contemplated within the spirit and scope of the invention as claimed.

What claim as new is:

l. A tire tool adapted for use in connection with an ordinary portable jack for forcibly removing a pneumatic tire from its rim, comprising an yopen elongated frame having spaced rim-flange engaging prongs at one end, means carried by the frame and engageable with rim ange to hold said prongs in engagement with said ilange, the

other end of said frame forming a jack abutment.'

and a presser foot member slidable in the frame and provided at its inner end with a part forming a second jack abutment, presser oot meinber having a presser foot at its outer end movable in a plane between the prongs of the frame and engageable with the tire behind said rim flange, whereby upon extension of the jaclr. engaged with said abutment, the presser foot member will be projected to force the tire from the rim.

2. A tire tool adapted for use in connection with an ordinary portable jaclr for forcibly removing a pneumatic tire from its rim, comprising an open elongated frame having spaced rim-flange engaging prongs at one end, means carried by the frame and engageable with the rim ange to hold said prongs in engagement with said flange, the other end of said frame forming a jack abutment, and a presser foot Amember slidable in the .frame and provided at its inner end with a part forming a second jack abutment, said presser foot member having a presser foot at its outer end movable in a plane between the prongs of the frame and engageable with the tire behind said rim flange, whereby upon extension of the jack engaged with said abutment, the presser foot member will be projected to force the tire from the rim, said first-named means comprising clamping lugs plvoted to the frame adjacent to and inwardly of said prongs.

3. A tire tool adapted for use in connection with an ordinary portable jack for forcibly removing a pneumatic tire from its rim, comprising an Yopen elongated frame having. spaced rim-flange engaging prongs at one end, means carried by the frame and engageable with rim flange to hold said prongs inengagement with said flange, the other end of said frame forming a jack abutment, and a presser foot member slidable in the frame and provided at its inner end with a, part forming a second jack abutment, said presser foot member having a presser foot at its outer end movable in a plane between the prongs of the frame and engageable with the tire behind said rim flange, whereby upon extension of the jack engaged with said abutment, the presser foot member will be projectedto force the tire from the rim, said frame being oi substantially U- shape and having outwardly converging outer ends the terminals of which form said prongs.

4. A tire tool adapted for use in connection with an ordinary portable jack ior forcibly removing a pneumatic tire irornits rim, comprising an open elongated frame having spaced rimilange engaging prongs at one end,'means carried by the frame and engageable with rim flange to hold said prongs in engagement with said ilange, -the other end of said frame forming a jack abutment, a presser foot member slidable in the frame and provided at its inner end with a part forming a second jack abutment, said presser foot member having a presser foot at its outer end movable in a plane between the prongs of the frame and engageable with the tire behind said rim ilange, whereby upon extension of the jack engaged with said abutment, the presser foot member will be projected to force the tire from the rim, said presser foot member comprising a bar arranged intermediate the sides of the frame and slidably mounted in the latter, a guide for said bar, and a compression spring inter-posed between said guide and the secondnamed jack abutment for normally yieldingly retracting said presser foot member.

5. A. tire tool adapted for use in connection with an ordinary portable jack for forcibly removing a pneumatic tire from. its rim, comprising an open elongated frame having spaced rimflange engaging prongs at one end, means carried by the frame and engageable with rim ange to hold said prongs in engagement with said flange, the other end of said frame forming a jack abutment, and a presser foot member slidable in the frame and provided at its inner end with a part forming a second jack abutment, said presser foot member having a presser foot at its outer end movable in a plane between the prongs of the frame and engageable with the tire behind said rim ange, whereby upon extension of the y jack engaged with said abutment, the presser foot member will be projected to force the tire from the rim, said second-named jack abutment comprising a cross head having end slots slidably engaging the sides of the frame so as to be guided by the latter,
